"cemeg" in context

Yng Nghymru, mae'n orfodol i fyfyrwyr ysgol astudio cemeg hyd at lefel TGAU (16 oed).

In Wales, it is compulsory for students to study chemistry at GCSE level (16 years old).

Rwy'n meddwl hefyd ei bod yn bwysig peidio â darogan gwae ynghylch y pethau hyn, gan nad yw'r heriau yn unigryw i'r Gymraeg—maent yr un peth ar gyfer ffiseg, cemeg, ond maent yn waeth o ran recriwtio cyfrwng Cymraeg.

I think it is important as well not to have a counsel of doom on these things, because the challenges aren't unique to Welsh—they're the same for physics, chemistry, but they're worse when it comes to Welsh-medium recruitment.
